hive-vault
Your AI coding assistant forgets everything between sessions. Hive fixes that.
Hive is an MCP server that connects your AI assistant to an Obsidian vault. Instead of loading everything upfront, it queries only what's needed — on demand.
| Metric | Without Hive | With Hive |
|---|---|---|
| Context loaded per session | ~800 lines (static) | ~50 lines (on demand) |
| Token cost for context | 100% every session | 6% average per query |
| Knowledge retained between sessions | 0% | 100% (in vault) |
Measured on a real vault with 19 projects, 200+ files. See benchmarks.
Quick Start
Hive runs without a vault — vault tools return a friendly error until VAULT_PATH is set, so you can install first and configure later.
# Minimal — uses default vault path ~/Projects/knowledge
claude mcp add -s user hive -- uvx --upgrade hive-vault
# With a custom vault path
claude mcp add -s user hive -e VAULT_PATH=$HOME/path/to/vault -- uvx --upgrade hive-vault
# Gemini CLI
gemini mcp add -s user -e VAULT_PATH=$HOME/path/to/vault hive-vault uvx -- --upgrade hive-vault
